Looking at my TRAINS issue the Eastbound Hump has in fact two leads. There is a crossover (X) just past the hump on the downhill part into the bowl tracks. The Westbound Hump has only one lead.
Looking at Google Earth, I'll try my best to point out each yard: (Going from North to South or Top to Bottom)
The top most yard with the balloon track is called the "Spare Yard" (tracks 700-718), this is where UP holds unit coal cars for the Powder River Basin that aren't needed or used. The next yard down is the "Westbound Run-Through" (tracks 276-293) followed by the "Westbound Departure Yard" (tracks 304-313). Note we are moving a bit East for the next few yards. Then you have the "Westbound Classification Yard (Westbound Hump)" (tracks 011-060). Below that is the "Westbound Receiving Yard" (tracks 221-229). Below that is the "Car Repair Shop and Yard" (tracks 501-505) and the "Company Storage Material" (tracks 414-421) just to the West of the Car Shop. Immediately to the East of the Car Shop is the "Van Yard" (tracks 202-212). Cutting the yard in the middle are the 3 "Run Though" Tracks. Below the run though tracks are the "Eastbound Classification Yard (Eastbound Hump)" (tracks 101-164), and to the East is the "Eastbound Departure Yard" (tracks 301-306). To the West of the Eastbound Hump is the "Eastbound Receiving Yard" (tracks 201-209). And at the very bottom is the "Diesel Repair Shop, Wash House, Supply Department, Locomotive Support and Storage Tracks." The building near the bottom and to the right of the Engine Shops are "Main Office, Bailey Command Center."
There at least 6 towers in Bailey:
East Hump Tower.
West Hump Tower.
Route Selection Tower.
East Trim Tower.
West Trim Tower.
"Area 51" Control Plant.
All operate under the Bailey Command Center.
The Remote Control areas are:
West Hump North Pullback (Zone 1), West Hump South Pullback (Zone 2), Coal Spare Yard (Zone 3) West Trim North Pullback (Zone 4), West Trim South Pullback (Zone 5), Van Yard (Zone 6).
As for signals and whatnot I'm lost when it comes to that. I'll try to dig some stuff up though.

Quote from a new UP employee going to Bailey: "I flew out here at night. I looked out the window and said, 'That must be the city of North Platte.' They said, 'No, that's the rail yard.'"
Building Bailey even in a smaller version is still a undertaken, good luck.
